..Twelve Case Reports (LOE 5) and six review articles (LOE 5) were found. Based on these findings, it appears that few high level studies have been published in the past 34 yr related to the success and failure of endodontic retreatment...

..3% NaOCl as a root canal irrigant and MTAD as a final rinse was significantly more effective against E. faecalis than the other regimens. The chi2 test showed no difference between the other regimens...

The effect of various concentrations of sodium hypochlorite on the ability of MTAD to remove the smear layer

..We found no significant difference in dye leakage between resected MTA (Group 1) and non-resected MTA (Group 2). Based on these results it appears that the resection of set MTA does not affect its sealing ability...

The effect of calcium sulfate on hard-tissue healing after periradicular surgery

..005). There was an inverse association between dentin bridge formation and inflammatory cell infiltration (p = 0.001). Based on these results, it appears that hyperglycemia adversely affects pulpal healing in rats...

..The results clearly showed that although the addition of chlorhexidine did not negatively impact the efficacy of MTAD, the substitution of this antimicrobial agent for doxycycline significantly reduces the efficacy of the solution...

The antimicrobial effect of biopure MTAD on eight strains of Enterococcus faecalis: an in vitro investigation

..The solubilizing effects of MTAD on pulp and dentin were somewhat similar to those of EDTA. The major difference between the actions of these solutions was a high binding affinity of doxycycline present in MTAD for the dentin...

Outcomes of nonsurgical retreatment and endodontic surgery: a systematic review

..The purpose of this systematic review was to compare the clinical and radiographic outcomes of nonsurgical retreatment with those of endodontic surgery to determine which modality offers more favorable outcomes...

A comparison of cone-beam computed tomography and direct measurement in the examination of the mandibular canal and adjacent structures

..treatment question: should a tooth be saved through root canal treatment and restoration (RCT), be extracted without any tooth replacement, be replaced with a fixed partial denture (FPD) or an implant-supported single crown (ISC)?..

Revitalization of tooth with necrotic pulp and open apex by using platelet-rich plasma: a case report

..Subjects rated their discomfort after needle punctures utilizing the visual analog scale pain scoring system. There was no statistically significant difference in the pain perception using the DASD versus the control device...

Accuracy of cone-beam computed tomography and periapical radiography in detecting small periapical lesions

..The aim of this study was to determine the diagnostic accuracy of 2 cone-beam computed tomography (CBCT) machines and periapical (PA) radiography in detecting simulated apical lesions created with the smallest dental burs available...

..Various methods have been used to remove the smear layer. Conflicting results have been obtained from numerous in vitro studies regarding the significance of the presence or the removal of the smear layer...

Contemporary endodontic surgery

Richard RubinsteinDepartment of Endodontics, University of Pennsylvania School of Dentistry, USAJ Calif Dent Assoc 32:485-92. 2004

..This article describes the role of these advances in contemporary endodontic surgery...

..The purpose of this study was to use blood clots and platelet-rich plasma (PRP) as scaffolds in regenerative endodontics under ideal conditions in a ferret model to examine the tissues generated within the root canals...

Comparison of efficacy of pulverization and sterile paper point techniques for sampling root canals

..The purpose of this study was to compare the efficacy of the pulverization and sterile paper point techniques for sampling root canals using 5.25% NaOCl/17% EDTA and 1.3% NaOCl/MTAD (Dentsply, Tulsa, OK) as irrigation regimens...

..The purpose of this study was to compare the amount of bleeding from soft tissue and bone in pig jaws after preoperative intraosseous or infiltration anesthesia with 2% lidocaine containing 1:50,000 epinephrine...

..Clinicians are confronted with difficult choices regarding whether a tooth with pulpal and/or periapical disease should be saved through endodontic treatment or be extracted and replaced with an implant...

..05). Samples treated with MTAD yielded significantly less leakage than samples treated with sodium hypochlorite. The amount of dye penetration was not statistically different between teeth treated with MTAD or EDTA (p = 0.062)...
